QUESTO – An Ontology for Questionnaires
Abstract
QUESTO is an ontology formalizing questionnaires and related entities, such as the processes of administering the questionnaire or capturing the answers. It is built according to the OBO Foundry methodology and is a component of an ontological model that aims to enable interoperability between various clinical data sources in the context of a Learning Health System. This article presents the main entities of QUESTO and provides an example of its application: a relational data model is generated from the ontology and used to retrieve data from public health questionnaires stored in a REDCap database.
